Part A:

Electricity Company | Rate Charged | Rate Rounded |

Atlas Energy 12.065 12.070

Big City Light 9.138 9.140

Connex 9.143 9.140

Dynamon Power 9.707 9.710

ElectriCo 9.503 9.500

Part B:

Big City Light and Connex.

Part C:

Two companies can have the same rate when they are rounded because two numbers can be rounded to the same number although they are different numbers. For example; 9.138 and 9.143 can both be rounded to 9.140.

A right circular cylinder has a height of 22 1/4 ft and a diameter 2 2/5 times its height. What is the volume of the cylinder? E

Triss [41]

Answer:

The volume of cylinder is:

49806.06 ft^3

Step-by-step explanation:

We are given a right circular cylinder with:

Height(h)= $22\frac{1}{4}ft=\dfrac{89}{4}ft$

and a diameter is $2\frac{2}{5}$ times it's height.

i.e. $\dfrac{12}{5}$ times it height.

i.e. the diameter is given as:

$\dfrac{12}{5}\times \dfrac{89}{4}=\dfrac{267}{5}ft.$

We know that the radius of cylinder is half the diameter.

Hence, radius(r) of cylinder is:

$\dfrac{1}{2}\times \dfrac{267}{5}\\\\=\dfrac{267}{10}$

The volume(V) of cylinder is given by:

$V=\pi r^2h$

$V=3.14\times (\dfrac{267}{10})^2\times \dfrac{89}{4}\\\\V=\dfrac{19922423.94}{400}\\\\V=49806.06ft^3$

Hence, the volume of cylinder is:

49806.06 ft^3

Is this number written in scientific notation 4.8•100^7

Ne4ueva [31]

No this number is not written in scientific notation
In scientific notation, it'll look like
4.8 * 10 ^14

In scientific notation it's 10 ^ n
NOT 100^n

Hope this helps
